Hypothesis

Does small body weight increase the risk of tenofovir-associated renal dysfunction in HIV-infected patients?

Conclusion

Small body weight is an independent risk factor for tenofovir-associated renal dysfunction in Japanese patients.

Supporting Evidence

  • 19.6% of patients experienced tenofovir-related renal dysfunction.
  • Tenofovir-related renal dysfunction occurred at an incidence of 10.5 per 100 person-years.
  • Smaller body weight was significantly associated with renal dysfunction.
  • Older age and concurrent smoking were also identified as risk factors.
  • Patients with a median weight of 63 kg were analyzed.

Takeaway

If you're small and take a medicine called tenofovir for HIV, you might need to be extra careful because it can hurt your kidneys.

Methodology

Retrospective cohort study analyzing Japanese HIV-infected patients on tenofovir therapy.

Potential Biases

Selection bias may have led to an underestimation of the incidence of renal dysfunction.

Limitations

The study is retrospective and lacks a control group for comparison.

Participant Demographics

Median age 38 years, 95.2% male, median weight 63 kg.
